One very controversial component of Scientology is its drug treatment program, Narconon. Tom Cruise, in an interview with Der Speigel quoted here, called it "only successful drug rehabilitation program in the world."

Cruise: I'm a helper. For instance, I myself have helped hundreds of people get off drugs. In Scientology, we have the only successful drug rehabilitation program in the world. It's called Narconon.

SPIEGEL: That's not correct. Yours is never mentioned among the recognized detox programs. Independent experts warn against it because it is rooted in pseudo science.

Cruise: You don't understand what I am saying. It's a statistically proven fact that there is only one successful drug rehabilitation program in the world. Period.
